Baader Hyperion 13 mm

The field of view of Baader Hyperion eyepieces is 68° - exactly the distance your eyes can see without moving. The 8-member lens system, arranged in five groups, gives a sharp, colour-free image across the entire field of view, with a comfortable eye relief of 20 mm. Its grain-like lens materials and anti-reflective coating adapted to their type provide outstanding light transmission and colour fidelity. Anti-reflective latches make it ghost-free. On top of the eyepiece, there is an M43x0.75 thread for mounting various cameras.

The 21 mm eyepiece gives a similar sky field as a 32 mm Plössl, but the higher magnification makes the sky more spectacular.

They have a 1.25" focuser, although their design allows them to fit into a 2" one. The Hyperion 31mm and 36mm eyepieces offer the maximum in a 2" focuser: although they have a 1.25" adapter, increased vignetting is expected in this size of eyepiece.
